Script error under PHP 4.3.3

[Andrew Banks]

Could anyone identify why the following script is giving me various errors
under php 4.3.3. It worked fine on previous versions.

function cut_string($str ing,$wordnum,$t rail)
{
$string_arr=exp lode(" ",$string);
for($i=0;$i<$wo rdnum;$i++)
{
$re_string.= " ".$string_a rr[$i];
}
$str= $re_string.$tra il;
print $str;
}

Thanks in advance

Post the 'various errors'.

Compiles fine here under 4.3.3. If it's giving errors at runtime, post
examples of data that cause them, and the errors themselves.

### check wordnum against actual number of words in string_arr
if ($wordnum > count($string_a rr)) $wordnum = count($string_a rr);

### and please, please, please initialize re_string
$re_string = '';

If you'd tell us what the errors are it might be easier to tell you why
they show up.

I imagine that $wordnum > count ($string_arr) for the set of parameters
you're passing to this function. You need to modify your routine to count up
to $wordnum only if count ($string_arr) >= $wordnum.
